Virtual grasping recognition based on prior knowledge in an AR system

In order to solve the real-time problem and the misjudgment of the traditional method,the virtual grasping recognition algorithm based on prior knowledge is introduced in an augmented reality(AR).Through analyzing a large number of experiment datas,the key datas are extracted and processed,the decision tree is constructed.A new kind of collision detection method based on data-fitting have been use to realize the recognition of grasping.The experiment results show that the algorithm has high recognition rate,well real-time,and the process of interaction is natural,which satisfies the requirement of interaction in AR system.
